DEODORIZER.

Specification of Letters Patent.

Patented July 10, 1917.

Application filed April 17, 1917. Serial No. 162,631.

To all whom it may concern:

Be it known that I, BERT W. FLANDERs, a citizen of the United States, residing at New London, in the county of New London and State of Connecticut, have invented new and useful Improvements in Deodorizers, of which the following is a specification.

This invention relates to refrigeration, and more especially to air coolers and deodorizers which include a fan or other means for pumping air into contact with water or other liquid before it is delivered to the point of use- The object of the invention is to produce an attachment for application more especially to the cage of an ordinary cooling fan, and which attachment'includes a reservoir for water or a deodorizing liquid, a moistening surface with a fabric sheet hanging in front of the fan, and means for delivering the liquid as rapidly as may be desired to said surface so that the air from the fan is blown against the moistened fabric and cooled or treated with a deodorizer before it reaches the point of use.

Details will be found in the following specification, reference being had to the accompanying drawings forminga part of the same and in which Figure 1 is a perspective view of a fan in outline only, showing this attachment applied to its cage.

Fig. 2 is an enlarged front elevation of the attachment, partly broken away and in section.

Fig. 3 is an end elevation of the cage and the attachment, showing the drum rotated so as to terminate the feed of the liquid.

Fig. 4 is a sectional detail to show the means for regulating the outflow of the liquid from the drum.

In the drawings I have used the letter F to designate a fan of the common and well known type, and C its guard or wire cagethis being the ordinary article of domestic and oflice use andconstituting no part of the present invention. To the frame or cage of such a fan my attachment is capable of application. For this purpose I provide a support in the form of a bail 1 of wire or the like, preferably having a hook 2 which may be passed over the upper portion of the cage, and from said hook its arms diverge downward and at their lower ends are turned inward as at 3 and into bearings 4 in the extremities of a cylindricalv reservoir or drum 5, one end of the same having a pro ecting flange 6 provided with diametrically opposite notches 7 into which the corresponding arm of the bail fits when this drum stands in either of two positions. At an appropriate point in what might be called the top of the drum is a filling openmg 8 closed by a cap or plug 9, and from time to time water or deodorizing or cleansing liquid is poured into the drum through th s opening and the same closed. The drum will probably be of metal, and its capacity 1S'a matter of no moment as-far as the present specification is concerned. Of course when it is being filled the proper notch 7 is engaged with the bail to hold the filling opening at the top, but at other times the bail may be disengaged from this notch and the entire drum rotated on its bearings so that the other notch engages the bail, when the filling opening is at the bottom although closed by its plug.

In what might be called the bottom of the drum I provide a series of openings 10, preferably three in number throughout the length of a drum of a size adapted to the ordinary fan, and in corresponding openmgs directly above those numbered 10 are sleeves 11 as best seen in Fig. 4. Through each sleeve is passed the threaded portion of a bolt 12 whose upper end receives a wing nut 13 above the drum 5, while its lower portionpasses down loosely through the openings 10 and has a head 14: at its lower extremity. On the shanks of the several bolts and over their heads is mounted a strip 15 which serves in the nature of a washer as will be seen below. ()verlying the stri is a strip of felt as shown at 16, its width eing about the same as that. of the metal strip. Next above the felt is one edge of a sheet of fabric 17, which fabric is preferably cheese cloth or other material of rather coarse mesh, and by In'efmencc this sheet is about square so that it may hang over the lower portion of the cage C when the fan is not running, or will flutter outward from the cage when the fan is running as seen in Fig. 1. The felt strip and the fabric sheet are threaded onto the bolts 12 above their heads 14, and the fabric comes up under the body of the drum 5 at the bottom and overlies the holes 10, or at least that portion of said holes which is not filled by the bolts. When now the wing nuts are adjusted to draw the bolts upward, their heads raise herein, I do not wish to be limited.

the plate or strip 15 which in turn lifts the felt strip '16, and said sl rip in turn lifts the fabric sheet 17 so that the latter is pressed close against the bottom of the drum and in effect closes the outlet opening 10. ()n the other hand, reverse movement of the wing nuts permits the bolts 12 to descend, with the result that the openings are more or less freed of the choking or checking action due to the adjustment just referred to. Thus it will be seen that the operator is at liberty to permit the liquid within the drum to flow through these openings more or less rapidly, or to practically cut off the flow entirely. \Vhen it does flow out, it passes onto the fabric sheet and follows down the same by capillary attraction, and as the fan blades rotate and a blast of air is set up through the front of the cage C, the fabric will flutter in the breeze as indicated in Fig. 1 and of course the air delivered by the fan will become moistened and cooled if cold water is employed or to a greater or less extent impregnated with deodorizer. lVhere I speak of deodorizing As has been suggested. cool or perhaps cold water might be employed and the air merely chilled thereby. If a disinfectant liquid is employed, or a deodorizing liquid, the corresponding result will of course be obtained. The liquid might be perfumed if preferred. In any event it is clear that the air from the pump, fan, or other source of supply is directed against the fluttering sheet of fabric, and this sheet is supported at its upper edge by my attachment against the outlet of a tank or reservoir which contains the desired liquid, and means are present to regulate the supply of liquid thereto. If the rotation of the fan be stopped, the moistened sheet still hangs in the air and its medicinal or other properties are given off by evaporation and into the air currents during the normal circulation within the apartment, but it is clear that when the air is set in motion mechanically the effect of the operation will be greater because the diffusion of the odors due to the evaporation of the liquid on the fabric will be more rapid.

While I have shown and described this device as an attachment, and particularly an attachment to the cage of an ordinary domestic or otlice fan, it is quite clear that it might be built as a permanent part of the fan, pump, or other source of air suppl if the same were devised and constructed on a larger scale. \Vhile I have shown three bolts for adjusting the washer or strip 115, a longer drum will require a greater number. The obvious purpose of the felt strip is to serve as a cushion between the metal strip and the bottom of the tank. Further details may safely be left to the manufacturer,

and the sizes and materials of parts are not essential. I

()ne detail which l reserve the right to cm ploy if thought advisable is a means for venting the lilling opening to allow the admission of air to take the place of the liquid drawn out of the tank, while not permitting the liquid to run out the vent when the cylinder is reversed. As shown in the drawings, a fine pipe 20 is connected with the filling opening, which latter is as usual surrounded by a nipple 21 through whose side this pipe opens, leaving the-plug or cap entirely above the pipe; and the latter is carried around the drum for fully one half of its circumference, its lower end :32 being left open. \Vhen now the drum stands upright with the filling opening at the top, the extremity 22 of the pipe is at the bottom, and as liquid runs out of the drum air. is admitted through the pipe to take its place. \Vhen it is desired to shut off entirely the flow of liquid out the opening 10, the bail is sprung to disengage the notch as shown in the drawings and the entire drum rotated on its trunnion for half a revolution to bring the openings 10 at the top. During this rotation the tube of course follows the movement of the drum, but no liquid, can escape from it because its extremity 22 moves to the top at this time.

What is claimed as new isz- 1. The herein described (lGOdOIlZlDQ' apparatus for insertion in a draft of air, the same comprising a substantially cylindrical tank mounted in a horizontal axis and having a row of openings along its normally lower side, a fabric sheet whereof one edge overlies said openings and the remainder hangs free, means for controlling the flow of liquid out the openings onto the sheet, a filling nipple at the normally upper side of the tank, a pipe leading from said nipple half way; around the tank for venting the tank, a plug for closing said nipple, and means for rotating the tank on its axis, for the purpose set forth.

2. The herein described deodorizing attachment for fans and the like, the same comprising a bail having a hook for engagement with the fan-cage and the ends of its arms inturned, a horizontal cylindrical drum having hearings on both extremities rotatably mounted on said inturned ends and having a flange at one extremity notched at diametrically opposite points to engage the adjacent arm of the yoke, the drum having a filling nipple opposite one notch and a series of outlet openings through its wall in line with the other notch, a fabric sheet having one edge overlying said openings, means for pressing it against the same with varying force to regulate the supply of liquid to the sheet, and means for closing said filling nipple 50 that the drum may be rotated to place the outlet openings at the top, for the purpose set forth.

3. The herein described deodorizing attachment for fans and the like, the same comprising a bail having a hook for engagement with the fan-cage and the ends of itsarms inturned, a horizontal cylindrical drum having bearings on both extremities rotatably mounted on said interned ends and having a flange at one extremity notched at diametrically opposite points to engage the adjacent arm of the yoke, the drum having a filling nipple opposite one notch and a series of outlet openings through its wall, in line with the other notch, a fabric sheet having one edge overlying said openings, means for pressing it against the same with varying force to regulate the supply of liquid to the sheet, a pipe leading from said nipple half-way around the tank for venting the latter, and means for closing said nipple when desired.

4. The herein described deodorizing attachment, the same comprising a cylindrical drum having along its normally lower side a series of outlet openings and in its upper side a series of openings alined therewith and a filling orifice closed by a plug, a metal strip beneath the lowermost openings, a soft stri p overlying the metal strip, a fabric sheet having one edge overlying the soft strip, and a. series of rods whereof each eX- tends vertically through a pair of said openings and the sheet and soft strip and is connected with the metal strip at its lower end, and means for adjusting the rod vertically with respect to the cylinder, for the purpose set forth.

In testimony whereof I affix my signature.
